Cannot locate recently installed program

Yes that guide was given to me on the EndeavorOS Telegram channel. Quite helpful. The only thing is, I don’t believe this part is possible, and the telegram users seemed to agree:

Don’t reset or hard power off your system - It causes filesystem corruption and other issues. Don’t do it. Be sure to enable Sysrq which allows you to use REISUB if your system freezes.

This is because sometimes power will be cut to your house, for one reason or another. If your computer was running during that time, it’s going to do a hard reset. I think this probably happens to most people. I do intend to get a battery backup to plug into, but right now I have to wait on available funds.
